It's oh so quiet……..

Ventrolla PSS reduces noise levels

Sliding sash windows normally require at least 3mm of perimeter gap to slide properly. In an average sized window of 1.2m x 1.8m, the aggregate gap area would be 15cms x 15cms, amounting to 1% of the area of the window.

The Ventrolla Perimeter Sealing System (VPSS) eliminates this air gap and, under live tests, achieved a noise reduction in the 6 – 10dB range which, in acoustic terms is deemed as ‘significant’.

Whilst VPSS can provide a positive impact on noise reduction, this should be viewed as an added benefit rather than as a solution to a particular external noise problem. For such problems, secondary glazing options should be considered.
